To reduce the high wind oscillatory surge impact on the high-precision pressure sensor under sand collecting box, improve sand collecting amount real-time of sand-taped instrument
Certainty of measurement, and the high efficiency separation of air-flow and sand and dust can be reached, belong to soil drifting test and control field.
Background technology
The research of soil drifting is the pass between silt discharge and wind speed by wind comfort and field inspection foundation
System, the measurement apparatus of its core is sand-taped instrument, and sand-taped instrument is provided with the husky unit of several collection on differing heights, is used to measure
The particular instrument of the regularity of distribution of soil movement granule in vertical cross section air-flow, can observe the soil wind of deflation basin by it
Erosion amount.Therefore, the sand-taped instrument seeking science just seems particularly significant.
Existing sand-taped instrument, a class be the sand collecting box of the differing heights on sand-taped instrument be dismountable, measure in the wild
After a period of time, being pulled down by sand collecting box and bring back laboratory and carry out weighing of sand and dust, this sand-taped instrument causes research worker not obtain
Observe data to continuous print, and add artificial work to a certain extent.Although an other class sand-taped instrument is at sand collecting box
It is arranged with pressure transducer, the weight of sand and dust in sand collecting box can be measured in real time, but owing to there is soil drifting area
Mean wind speed is the biggest, and particularly under high wind effect, air-flow vibration has bigger shadow to the certainty of measurement of pressure transducer
Ring, and this sand-taped instrument and video data terminal wired connection, it is difficult to obtain for a long time the purpose of wind erosion data in the wild.
Measure the most in real time to realize the long-term of sand-taped instrument, it is to avoid the high wind vibration disturbance to pressure transducer, improve
The certainty of measurement of sand-taped instrument, utilizes the air-flow principle that reversely liquidates sand-taped instrument collects husky cellular construction to have carried out brand-new design,
The stream entering the husky unit of collection can be divided into two strands of anti-phase air-flows by this collection sand unit, and occurs repeatedly in the husky unit of collection
Anti-phase liquidate, thus reduce the speed of air-flow, air-flow impulsive disturbance to pressure transducer is finally reduced or eliminated, improve collection sand
The certainty of measurement of instrument；The most anti-phase air-flow liquidated in the husky unit of collection simultaneously so that the sandy environment that two bursts of direction of motion is contrary
Carry out frictional impact, reduce the kinergety of sand and dust, it is achieved air-flow and the high efficiency separation of sand and dust.Sand-taped instrument is provided with
The signals collecting terminal of radio sensing network, for receiving the data value of the pressure transducer under the husky unit of collection, does long-range
Public room is connected with the acquisition terminal of sand-taped instrument by wireless network, the soil drifting of acquisition sand-taped instrument measurement that can be real-time
Amount.
